Abstract

A method for preparing a treated cellulosic material comprising: providing a cellulosic material; a treatment protocol comprising impregnating the cellulosic material with an aqueous dispersion comprising a polybutene and a stabilizing agent.

Claims

exact text as granted — not AI-modified
1 . A method for preparing a treated cellulosic material comprising:
 (a) providing a cellulosic material;   (b) a treatment protocol comprising impregnating the cellulosic material with an aqueous dispersion comprising a polybutene and a stabilizing agent.   
     
     
         2 . The method of  claim 1 , wherein the polybutene has a molecular weight of less than 3000. 
     
     
         3 . The method of  claim 1 , wherein the stabilizing agent is a non-ionic or an anionic surfactant or a mixture of both. 
     
     
         4 . The method of  claim 1 , wherein the impregnating step of the treatment protocol is conducted under pressure greater than or lower than ambient. 
     
     
         5 . The method of  claim 1 , further comprising impregnating the cellulosic material with an additive. 
     
     
         6 . The method of  claim 1 , wherein the aqueous dispersion contains from 5 to 75 weight percent solids. 
     
     
         7 . The method of  claim 1 , further comprising drying the treated cellulosic material. 
     
     
         8 . The method of  claim 1 , wherein the average particle size of the solids in the aqueous dispersion is less than 50 microns.
